Example 6 with EndpointState

use of com.couchbase.client.core.endpoint.EndpointState in project couchbase-jvm-clients by couchbase.

the class PooledServiceTest method retriesRequestIfEndpointCannotConnect.

/**
 * With direct dispatch in the pool it is possible that endpoint for which the socket is
 * waiting for to be dispatched never goes into a connected state but rather into disconnected
 * (and then subsequent reconnect). As soon as we observe a disconnect state we need to retry the
 * op so that it has a chance to complete somewhere else.
